These raw materials are inti mately blended mixed with water and ground in an 11 x 36 foot raw grinding mill This results in a mix ture with the consistency of cream called slurry The slurry is fed into the 500 foot long by 15.5 foot di ameter wet process kiln Turned by two synchronous 300 hp variable speed motors the kiln is lined with
Step 2 : Proportioning Blending & Raw Grinding. The raw materials are analyzed in real-time using cross-belt analyzers and in the plant laboratory, blended in the proper proportion, and then ground even finer. Plants grind the raw materials with heavy, wheel-type rollers that crush the materials into powder against a rotating table.
Similar to the dry process, materials also need to undergo quarrying, primary crushing, secondary crushing, proportioning and grinding in the raw materials preparation stage of the wet process. The biggest difference between the two methods is that in the wet process, water is usually required as a process media added in the raw mix to form slurry.
Manufacturing Process: Crushing & Proportioning: Limestone rock is the principal raw material, the first step after quarrying in the processes is the primary crushing. Mountains of rock are fed through crushers capable of handling pieces as large as an oil drum.

The raw materials (limestone and clay) are subjected to such processes as, crushing, drying, grinding, proportioning, and blending or mixing before they are fed to the kilns for calcination or burning process. The crushing stage involves breaking the raw materials into small fragments that vary in size between 6-14 mm. Machines called Crushers ...
Cement manufacturing process phases flow chart.Aug 30, 2012 cement manufacturing process phase ii: proportioning, blending & grinding.Now cement plant grind the raw mix with the help of heavy wheel type rollers and rotating table.Rotating table rotates continuously under the roller and brought the raw mix in contact with the roller.
Grinding / mixing. Raw materials grinding and mixing can be performed on dry track with hammer or pendular mills – or on wet track with roller mills. The choice of grinding technology is made according to the raw materials used, the required grinding particle size and to the type of products to be manufactured.. Matters are then humidified in shaft mixers then stored in clay stores.
The grinding process is necessary since some of the raw materials are of bigger particle size. The outcome of the first process is mash or meal form of feed. The purpose of second process of feed milling is to soften the mash or meal feed through heat and moisture. The output of this process is conditioned mash feed.
